ice 远程调用，使用application类

[["java:package:com.demo"]]
module zhz
{
    struct Person{
    	string name;
    	string password;
    };
    dictionary<long,Person>PersonList;
    interface PersonInter{
    	void sendUser(Person p);
    	Person returnPerson();
    };
};

  ice文件添加一个Person对象，一个字典表，表中为person对象，另外是一个方法调用。

client.java

package test;

import org.apache.log4j.Logger;

import com.demo.zhz.Person;
import com.demo.zhz.PersonInterPrx;

            try {
                communicator().destroy();
            } catch (Ice.LocalException ex) {
				logger.error("run()", ex); //$NON-NLS-1$

                ex.printStackTrace();
            }

    private String str = "My name is alex J, monster fairy is my baidu ID, the ICE Demo is running now! 八月初十";
    
    public int run(String[] args) {

        if (args.length > 0) {
            System.err.println(appName() + ": too many arguments");

            return 1;

        PersonInterPrx prx = PersonInterPrxHelper.checkedCast(communicator().propertyToProxy("Span.Proxy").ice_twoway().ice_timeout(-1).ice_secure(false));
// 这里会读取配置文件中的内容，找到对应的suibianjiao服务相关端口和协议，当然，配置文件中用span也可以，我们在服务端代码中写了对应代码。
        if (prx == null) {
            System.err.println("invalid proxy");

			if (logger.isDebugEnabled()) {
				logger.debug("run(String[]) - end"); //$NON-NLS-1$

            return 1;
        }
        Person holder = new Person();
        holder.name = "zhz";

        return 0;
    }

    public static void main(String[] args) {

			logger.debug("main(String[]) - start"); 		}

        Client app = new Client();
        int status = app.main("Client", args, "client.properties");// 这里加载配置文件
        System.exit(status);

		if (logger.isDebugEnabled()) {
			logger.debug("main(String[]) - end"); 
		}
    }
}
server.java

package test;

import org.apache.log4j.Logger;

import Ice.Application;

public class Server extends Ice.Application {
	/**

	 */
	private static final Logger logger = Logger.getLogger(Server.class);

	// class ShutdownHook extends Thread {
	// public void run() {
	// try {
	// communicator().destroy();
	// } catch(Ice.LocalException ex) {

			return 1;
		}

		if (interrupted()) {
			System.out.println(appName() + ": terminating");
		}

		Ice.ObjectAdapter adapter = Application.communicator()
				.createObjectAdapter("zhz"); // 这里的Span要和Server.config里的配置对应
		adapter.add(new PersonInterI(), Application.communicator()
				.stringToIdentity("test"));// 我们可以定义多个ID，这样也是没问题的，客户端找哪个Identity都可以。不过一般不这么用。
		adapter.activate(); // 激活Servant
		communicator().getLogger().print("Span Server is start ...");// 这里调用插件
		communicator().waitForShutdown();

		if (logger.isDebugEnabled()) {
			logger.debug("run(String[]) - end"); //$NON-NLS-1$

	}

	public static void main(String[] args) {

			logger.debug("main(String[]) - start"); //$NON-NLS-1$
		}

		Server app = new Server();
		int status = app.main("Server", args, "server.properties"); // 这里的配置文件没有写对应路径，所以运行程序的时候，要将配置文件打到ClassPath中
		System.exit(status);

		if (logger.isDebugEnabled()) {
			logger.debug("main(String[]) - end"); //$NON-NLS-1$

	}
}

 

 PersonInterI.java

package test;

import org.apache.log4j.Logger;

import Ice.Current;

import com.demo.zhz.Person;
import com.demo.zhz._PersonInterDisp;

public class PersonInterI extends _PersonInterDisp {
	/**
	 * Logger for this class
	 */
	private static final Logger logger = Logger.getLogger(PersonInterI.class);

	@Override
	public void sendUser(Person p, Current __current) {
		if (logger.isDebugEnabled()) {
			logger.debug("sendUser(Person, Current) - start"); //$NON-NLS-1$
		}
		 
		System.out.println("Person = "+p.name+":"+p.password);
		


		if (logger.isDebugEnabled()) {
			logger.debug("sendUser(Person, Current) - end"); //$NON-NLS-1$
		}
	}
	@Override
	public Person returnPerson(Current __current) {
		// TODO Auto-generated method stub
		return null;
	}

}

 个人认为跨语言有必要使用，如果都是java应用的话，不觉得没有必要，毕竟java的远程调用方式比较多。

以上例子需要安装slice2java的eclipse插件。。
